Audiobus: Use your music apps together.
What is Audiobus? — Audiobus is an award-winning music app for iPhone and iPad which lets you use your other music apps together. Chain effects on your favourite synth, run the output of apps or Audio Units into an app like GarageBand or Loopy, or select a different audio interface output for each app. Route MIDI between apps — drive a synth from a MIDI sequencer, or add an arpeggiator to your MIDI keyboard — or sync with your external MIDI gear. And control your entire setup from a MIDI controller.Download on the App Store
Audiobus is the app that makes the rest of your setup better.
Help me with handling iOS updates on my iPads
I now have those:
iPad Pro 9.7, iOS 12.4
iPad Pro 12.9, 2nd gen., iOS 12.4
iPad Air 3, iOS 12.2
Technically, I could still jailbreak both iPad Pros, as this seems to be possible with iOS 12.4
Originally, I planned to do this with the 9.7 Pro, let the 12.9 Pro stay at some iOS 12.x and would use iPadOS on the brand new Air.
But now, as the Air arrived with iOS 12.2, I have an iPad that not yet has the recent problems with IAA Apps!
That offers a way to... maybe let the Air at 12.2, still jailbreak the Pro 9.7 and install iPadOS on the 12.9 Pro.
What would you do?!?
